[Freeswitch-users] FreeTDM and Brazil DTMF - CallerID Detection

Hi, I would like to know if I can help, in someway, to implement this feature in FreeTDM. Today, if we use an analog card here in Brazil, we have to use dtmf to fsk converters to enable the callerid detection, both on freeswitch and asterisk. If there is anybody who works on FreeTDM / FreeSWITCH project that is available to help us with this, I can give access to an machine with analog boards, I have some knowledge in C programming too. Thanks.
